Abstract

The benefits that humans receive from nature are not fully understood. The ecosystem service framework has been developed to improve understanding of the benefits, or ecosystem services, that humans receive from the natural environment. Although the ecosystem service framework is designed to provide insights into the state of ecosystem services, it has been criticised for its neglect of spatial analysis. This thesis contains a critical discussion on the spatial relationships between ecosystem services and the urban landscape in Salford, Greater Manchester. An innovative approach has been devised for creating a landscape mosaic, which uses remotely-sensed spectral indices and land cover measurements. Five ecosystem services are considered: carbon storage, water flow mitigation, climate stress mitigation, aesthetics, and recreation. Analysis of ecosystem service generation uses the landscape mosaic, hotspot identification and measurements of spatial association. Ecosystem service consumption is evaluated via original perspectives of physical accessibility through a transport network, and greenspace visibility over a 3D surface. Results suggest that the landscape mosaic accuracy compares favourably to a map created using traditional classification methods. Ecosystem service patterns are unevenly distributed across Salford. The regulating services draw from similar natural resource locations, while cultural services have more diverse sources. The accessibility and visibility analysis provides evidence for the importance of urban trees as mitigators of ‘grey’ views, and urban parks as accessible producers of multiple services. Comprehensive ecosystem service analysis requires integration of quantitative and qualitative approaches. Evaluation of spatial relationships between ecosystem services and the physical landscapes in this thesis provides a practical method for improved measurement and management of the natural environment in urban areas. These findings can be used by urban planners and decision makers to integrate ecological considerations into proposed development schemes.
